DOORLOCK.

Application :filed November 23, 1925. Serial No. 70,739.

My present invention relates to .door locks and more particularly tolocks tor use on garage doors, shop doors and like places l where it isdesirable to make the door fast along its top and bottom edges and whereit is also desirable to effect the locking engagement automatically uponmoving the door into closed position, and my invention has for its mainobject the provision of an improved door lock of this class which willembody certain desired features of simplicity, efficiency andconvenience and which will be economical in manufacture.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements ot' partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part oi` this specification, and in which,

Fig. 9 represents a tace vi-ew taken on the line 9 9 ot Fig. 7.

lith more particular reference to the parts illustrated in theaccompanying drawings, 10 and 11 designate the cooperating` doors of thegarage 12, the doors being of any customary type hinged as at 13 toroutward swinging movement and one of the doors, herein illustrated asthe door 11, being furnished with a vertically extending` edge strip 13which suitably over-laps the adjacent edge o the door 10 whereby, whenthe doors are closed, to secure the door 10 in closed position by meansof the strip 13 on door 11. In the present exemplification, therefore,my improved lock is illustrated as applied to the door 11.

The preferred embodiment of .my invention as illustrated in theaccompanying drawings, comprises a center piece 14 having a base flange1.5 and a centrally pron jecting boss 16. This center piece is providedwith a central bore 11' offset inter mediate its length to provide ashoulder 18. Tui-nably fitting the bore 17 is a barrel 19 which is madewith a .shoulder 2Q adapted to butt against the shoulder 18 so as to prevent the removal of the barrel in a direction out through the boss 16.Said barrel 19 has a part 21 which protrudes beyond the extremity oi theboss 16, and this protruding part is provided with a diametricalaperture 22. The barrel 19 also protrudes for a distance beyond the baseend 15 of the center piece; and extending inwardly through thisprotruding part, which is designated by 23, is an opening 24 which ispreferably ot angular form in cross section for a reason presently toappear.

The center piece 141 is applied to the inner *face of the door 11 alongthe free edge thereor and midway the distance between top and bottomends of the door, the center piece being applied by placing the baseflange 15 flat against the inner tace of the door and itting theprotruding barrel portion 23 into a suitable opening 24 providedtransversely through the door 11, and, as herein illustrated, throughthe lapping edge strip 13. rThe center piece is rigidly secured to thedoor by means of screw elements 25.

The barrel 23 of the present invention may be operated from the outsideof the door by any suitable means; but the same has been especiallydesigned for use in connection with a lock 26 oi' the cylinder type,having a key operated rotatable barrel 27 with which is associated aprojecting bar 28. The lock 26 is applied in the usual way to the door11 with the rotatable barrel seated in the bore 24 and the bar 28,`which is of square formation in cross section, interlocking with thebarrel opening 24. By this arrangement the barrel 19 of the center pieceis connected with the key operated barrel 27 ci the lock, whereby thebarrel 19 will be rotated with the rotation of the barrel 27. A flexiblemember 29 in the form oi" a .chain is taken through the opening 22 orthe barrel 19 and is made fast to said barrel by means of .a pin 30arranged therein so as to engage one of the links ol1 the chain. vv@neend of this chain is Iattached to a latch 3l pivoted on a pin 32arranged in the. opposed lugs 34 of a bracket which is secured by meansof screw elements 3,6 adjacent the top edge of the door 11. The latch 31is yprovided with teeth 37 adapted to interlock with similar teeth pro'ided on keeper or catch 38 which is Vsuital'ily secured to the overheadtra-ming or wall 39. The `latch 31 is normally urged into position forengagement with its keeper by means Vot' a `pull spring 40 which has oneend secured at 41 to the baseoi the bracket and the. other end securedat 42 to the inner end ot the latch at a point inwardly ot the pin 32.The opposed lugs 34 are Vconnected by a back piece 43 which serves as astop against which the latch Iabuts under the influence ol lthe spring40. The pin 32 serves as a horizontal axis igor the latch so that whenthe barrel 19 is :turned causing the chain 29 to wind on the protrudingportion 21, the latch 3l will be withdrawn from its keeper.

The opposite or lower end ot the chain is attached to a drop latch 44movable 'on a pin 45 arranged on lugs 46 provided on a bottom,- bracket47 attached at the bottoni edge of thc door. 'lhe latch 44 is providedwith teeth 4S adapted to interlock with correspondingly termed teeth ona .keeper 49 which is secured to the floor-board 50 below the door. Thebracket 47 has a back piece 51 which serves as a stop to limit the down`ward movement ot the latch 44. ils `in the previous instance, the latch44 is withdrawn from its keeper when the chain `29 is turned upon theprotruding port-ion 21 under the turning n'iovement of the barrel 19.

To .open the door 11, the barrel 27 of the cylinder lock is operated bya key in the usual way with the. result that the barrel 19 is turned andthe chain winding on the protruding .portion 2l withdraws both the topand bottom latches from their keepers. llE the door is to be opened fromthe inside, it is only necessary to pull the chain towards the barrel 19or to turn the barrel 19 troni the insidev` eitherl el: which actionsresults in the withdrawal ot the latches from their keepers. `When thedoor is closed the latches 531 and 44 automatically interlock with theirkeepers; the top latch 31 being' normally held in position by the spring'for engagement with its keeper -while the botto-1n latch 44 drops ot'its own weight into position for engagement with its keeper.V Both thetop and bottom latches with their keepers are provided with suitablecooperating cam edges 52 and 53 to enable the latches to interlock withtheir keepers when the door 1l is closed.

While l have illustrated and described the preferred torna ofconstruction vcarrying my invention into efect, this is capable ofvariation :and modification without departing from fthe spirit of theinvent-ion. l', therefore, do not wish to be limited `to .the precisedetails yof `construction set lort'h, but desi-re 4to avail myself otsuch variations and modifications as come within the scope tot theappended claims.

'Having described `my inyention, what l claim as new and desire tosecure by Letters Pat-.ent is:

A .door lock of the kind set 'forth coniprising a key operated lock; ananisl bar-rel controlled by sai-d key operated lock v5 a pair of latchesarranged to interlock with keepers; and av flexible element extendingthrough said axis barrel and therewith turnahle and connecting saidlatches, substantially as described.

3. In a door and in coinb-ination, a lock provided with a key operatedbarrel; a center piece; a barrel having turning lit in said center pieceand extending therethrough; an operative connection between the centerpiece barrel and the "key operated barrel whereby to operate the formerfrom the latter; top and bottom brackets att-ached to the door; 'latchesp'ivoted to said bracket; and a kflexible element lextern'ling throughsaid barrel and attached at its opposite ends to said pivoted latches,substantially as described. f

4. In combination with a door and a floorboard; ot a barrel havii'ifl`rotatable support in the door and protruding tl-ieretroin; a bracketattached near the ltree edge ot the door; a latch pivoted to 'thebracket and adapted to interengage with a keeper; and a chain connectedto the protruding end olf said barrel and therewith turnable and.attached at one end to said latch, substantially as described.
